Abstract

The invention relates to a device ( 1 ) for providing a melt, in particular a plastic melt. Said device ( 1 ) comprises a feed unit ( 2 ) for material components, at least one purification unit ( 4 ) for the flowing melt, in particular a rotatable screening disc ( 5 ), and at least one sensor unit ( 17; 18; 19; 20; 21 ) for detecting one or more process parameters. The operation of the purification unit ( 4 ) can be influenced with the aid of said sensor unit, based on the filter-specific process data. The inventive device is configured in such a way that at least the type and dosage of the process materials that are supplied via the feed unit ( 2 ) and/or the processing parameters of said process materials can be controlled using the detected ( 17; 18; 19; 20; 21 ) process parameters and/or the filter-specific process data.

Description

Die Erfindung betrifft eine Vorrichtung mit einer Reinigungseinheit zur Bereitstellung einer Schmelze, etwa um diese in einer Kunststoffverarbeitungsmaschine oder dergleichen weiterverarbeiten zu können, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device with a cleaning unit to provide a melt, such as in a plastic processing machine or the like to further process, according to the preamble of claim 1.

Derartige Vorrichtungen dienen dazu, beispielsweise in Extrudern verwendete Kunststoffschmelzen mechanisch von Verunreinigungen zu befreien, um sie dann weiterverarbeiten zu können. Hierfür weist eine solche Vorrichtung etwa eine Reinigungseinheit mit einer metallischen Siebscheibe auf, die mit mehreren Siebeinsätzen, die über den Umfang aufeinander folgen, versehen ist. Die Siebeinsätze werden nach einer gewissen Funktionszeit einer Eigenreinigung ausgesetzt, um Verschmutzungen, welche die Lochkanäle zusetzen, zu entfernen. Ohne die Reinigung würde schnell ein erheblicher Gegendruck durch zugesetzte Siebbereiche entstehen, der die reinigende Funktion der Siebe für die Schmelze stören würde.such Devices serve, for example, used in extruders Mechanically free plastic melts from impurities, to then be able to process them further. For this purpose, such a device about a cleaning unit with a metallic screen disc on those with several sieve inserts, the above the circumference follow one another, is provided. The sieve inserts will be exposed to self-cleaning after a certain period of operation, to remove soiling, which can clog the hole channels. Without the cleaning would quickly a significant back pressure due to added sieve areas emerge, the purifying function of the sieves for the melt to disturb would.

Aus der WO 01/43 847 ist bekannt, zur Eigenreinigung die Siebeinsätze mit einem Reinigungsstrom zu beaufschlagen, welcher der Durchtrittsrichtung des Schmelzestroms durch die Siebscheiben entgegengesetzt ist. Dieser Gegenstrom wird in einem von dem Hauptschmelzekanal abgezweigten Rückspülkanal erzeugt. Um in Abhängigkeit vom Verschmutzungsgrad die Eigenreinigung der Siebeinsätze zu optimieren, wird dort eine Steuervorrichtung vorgeschlagen, die das Schmelzevolumen und/oder die Fließgeschwindigkeit der rückspülenden Schmelze bestimmt und deren Eingangsgrößen von während des Betriebes ermittelten Prozesspara metern gebildet sind. Eine derartige Vorrichtung kann jedoch auf wechselnde Qualität der zugeführten Komponenten nur mit angepasster Reinigungsleistung der Siebeinsätze reagieren, so dass unter Umständen, etwa bei verklumptem Ruß, der zugeführt wird, zwar die Siebeinsätze ihre Funktion erfüllen, jedoch die Ausgangszusammensetzung der Schmelze nicht den gewünschten Anforderungen entspricht.Out WO 01/43 847 is known, for self-cleaning with the sieve inserts to act on a cleaning stream, which the passage direction the melt flow through the screen discs is opposite. This Counterflow is diverted in one of the main melt channel Backwash channel generated. In order depending on Pollution degree to optimize the self-cleaning of the sieve inserts, There is proposed a control device which determines the melt volume and / or the flow rate the backwashing melt determined and their input variables of while formed by the operation process parameters are formed. A However, such device may be for changing quality of the supplied components react only with adapted cleaning performance of the sieve inserts, so that under circumstances, for example with clumped soot, which is supplied although the sieve inserts fulfill their function, however, the starting composition of the melt would not be the desired one Meets requirements.

Die Erfindung löst diese Aufgabe durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 sowie durch eine Vorrichtung mit den Merkmalen des Anspruchs 2, die einzeln oder in Kombination miteinander verwirklicht sein können. Hinsichtlich vorteilhafter Ausgestaltungen wird auf die weiteren Ansprüche 3 bis 6 verwiesen.The Invention solves this object by a device with the features of the claim 1 and by a device having the features of claim 2, which can be realized individually or in combination with each other. Regarding advantageous embodiments is based on the further claims 3 to 6 referenced.

Erfindungsgemäß ist in der Ausbildung nach Anspruch 1 die Möglichkeit eröffnet, aufgrund gemessener Parameter und ggf. daraus ermittelter filterspezifischer Prozeßdaten mit einer Änderung der zugeführten Prozeßmaterialien und/oder Prozeßrnaterialienzusammensetzung und/oder deren Verarbeitungsparameter reagieren zu können und somit eine gleichmäßige Qualität des Produkts auf der Ausgangsseite sicherzustellen.According to the invention is in the training according to claim 1 opens up the possibility due measured parameter and possibly determined therefrom filter specific process data with a change the supplied process materials and / or process material composition and / or their processing parameters to be able to react and thus a uniform quality of the product on the exit side.

In der Ausbildung nach Anspruch 2 kann andererseits auch bei nicht völlig gleichbleibenden Produkteigenschaften die Weiterverarbeitung angepaßt werden, etwa dadurch, dass in der Vorrichtung oder einer nachgeschalteten Weiterverarbeitungseinheit bei größer werdender Viskosität der Schmelze flexible Rohrquerschnitte erweitert oder Ventilöffnungszeiten verlängert werden, um die Fließgeschwindigkeit der dann zäher werdenden Schmelze und somit die Prozessführung konstant halten zu können.In The training of claim 2, on the other hand, not at completely constant product properties are adapted to further processing, approximately in that in the device or a downstream Further processing unit with increasing viscosity of the melt flexible pipe cross-sections can be extended or valve opening times extended, around the flow rate of then tougher expectant melt and thus to be able to keep the process control constant.

Besonders vorteilhaft beeinflußt die Regelung aufgrund der von der Sensoreinheit ermittelten Daten die Arbeit der Reinigungseinheit und die Regelung der Zusammensetzung der zugeführten Komponenten in wechselseitiger Abhängigkeit. Damit ist es beispielsweise möglich, wenn die Sensoreinheit einen zu geringen Rußanteil – und somit eine zu geringe Schwarzfärbung – in der Schmelze detektiert, sowohl die Eigenreinigung des Siebfilters zu erhöhen, weil Verklumpungen auf der Filtereingangsseite vorliegen können, als auch bei den zugeführten Komponenten den Rußanteil zu erhöhen, weil offensichtlich eine zu große Rußmenge im Siebfilter hängenbleibt und somit für das Produkt nicht zur Verfügung steht. Somit kann auch unterschiedlichen Qualitäten der zugefügten Komponenten Rechnung getragen werden.Especially favorably influenced the regulation based on the data determined by the sensor unit the work of the cleaning unit and the regulation of the composition the supplied Components in mutual dependence. That's it, for example possible, if the sensor unit too low soot - and thus too low Black coloring - in the Melt detected, both the self-cleaning of the mesh filter to raise, because Clumping on the filter input side may be present as also with the supplied Components the soot content to increase, because obviously too big soot gets stuck in the strainer and thus for the product is not available stands. Thus, also different qualities of the added components Be taken into account.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus einem in der Zeichnung dargestellten und nachfolgend beschriebenen Ausführungsbeispiel des Gegenstandes der Erfindung.Further Advantages and features of the invention will become apparent from a in the Drawing illustrated and described below embodiment the subject of the invention.

In der Zeichnung zeigt:In the drawing shows:

4 einen Schnitt entlang der Linie IV-IV in 3. 4 a section along the line IV-IV in 3 ,

In 1 ist schaubildlich und nach Art eines Blockschaltbilds eine Vorrichtung 1 dargestellt, welche die Merkmale sowohl des Anspruchs 1 als auch des Anspruchs 2 verwirklicht. Die Vorrichtung 1 umfasst eine Zuführung 2 für einen Input von verschiedenen Komponenten, etwa einem frischen Granulat, einem Recyclat, Masterbatchs oder Zuschlagstoffen wie z.B. Kreide, Holzmehl, Farbe usw. Die Komponenten werden über eine geeignete Plastifiziereinheit 3, hier als Trichter mit Förderschnecke dargestellt, zumindest einer Reinigungseinheit 4 zugeleitet. Diese kann, wie hier dargestellt, eine Siebscheibe 5 umfassen, die mit mehreren Siebeinsätzen 6 versehen ist. Typisch sind etwa zehn bis vierzehn Siebeinsätze 6, die auswechselbar sein können. In Reinigungsstellung ist die Siebscheibe 5 zwischen zwei parallelen Plattenkörpern 7, 8 innerhalb eines Reinigungskanals 9 gehalten, wobei in Flußrichtung 10 eines Reinigungsfluids (3) eine Beaufschlagungsöffnung 11 für die Beaufschlagung der Siebscheibe 5 vorgesehen ist.In 1 is diagrammatic and in the manner of a block diagram a device 1 which embodies the features of both claim 1 and claim 2. The device 1 includes a feeder 2 for an input of various components, such as a fresh granulate, a recyclate, masterbatches or aggregates such as chalk, wood flour, paint, etc. The components are via a suitable plasticizing unit 3 , here shown as a hopper with screw conveyor, at least one cleaning unit 4 fed. This can, as shown here, a screen disc 5 include that with several sieve inserts 6 is provided. Typical are about ten to fourteen sieve inserts 6 that can be interchangeable. In cleaning position is the sieve screen 5 between two parallel plate bodies 7 . 8th within a cleaning channel 9 held in the flow direction 10 a cleaning fluid ( 3 ) an admission opening 11 for applying the screen disc 5 is provided.

Im Ausführungsbeispiel hat die Siebscheibe 5 eine kreisrunde Umrissgestalt (4), und die Beaufschlagungsöffnung 11 weist zumindest eine erhebliche Erstrekkung in radialer Richtung der Siebscheibe 5 auf und reicht bis zu ihrem äußeren Rand. Die Siebscheibe 5 ist um eine zentrale Achse 12 drehbar, so dass die Siebeinsätze 6 nacheinander in den von der Beaufschlagungsöffnung 11 überstrichenen Bereich gelangen können.In the exemplary embodiment, the screen disc has 5 a circular outline shape ( 4 ), and the admission opening 11 has at least one significant Erstrekkung in the radial direction of the screen disk 5 and extends to the outer edge. The sieve screen 5 is about a central axis 12 rotatable so that the sieve inserts 6 successively in the from the admission opening 11 can reach over swept area.

Von dem Schmelzekanal 9 zweigt eine Rückspülleitung 13 ab, in der durch den Siebfilter 5 hindurchgetretene Schmelze mittels eines Schmelzeschusskolbens 14 in zur Flußrichtung 10 gegenläufiger Richtung 15 durch einen schlitzartigen Teilbereich 16 des Schmelzefilters 5 gepresst werden kann, um dadurch zugesetzte Löcher von Siebeinsätzen 6 zu reinigen. Somit kann der Schmelzefilter 5 während des Betriebes gleichzeitig auch seine Eigenreinigung betreiben und beispielsweise durch kontinuierliche oder getaktete Drehung um die Achse 12 jeweils teilweise in Eigenreinigungs- und teilweise in Filterstellung für die Schmelze stehen. Solche Bereiche, die sich in Filterstellung zumindest teilweise zugesetzt haben, können dann direkt der Reinigungsstellung zugeführt werden.From the melt channel 9 branches a backwash line 13 in, through the sieve filter 5 passed melt by means of a melted shot flask 14 in to the river direction 10 opposite direction 15 through a slit-like section 16 of the melt filter 5 can be pressed to thereby added holes of sieve inserts 6 to clean. Thus, the melt filter 5 at the same time operate its own cleaning during operation and, for example, by continuous or clocked rotation about the axis 12 each partially in Eigenreinigungs- and partially in filter position for the melt. Such areas, which have at least partially clogged in filter position, can then be fed directly to the cleaning position.

Die Vorrichtung 1 umfasst weiterhin mehrere Sensoreinheiten 17, 18 ,19, 20, 21, über die unterschiedliche Parameter erfasst werden, welche nicht nur zur Regelung der Funktion der Filtereinheit sondern auch zu Beeinflussung der Effektivität und der Qualität der Vorrichtung 1 herangezogen werden.The device 1 also includes several sensor units 17 . 18 . 19 . 20 . 21 , are detected on the different parameters, which not only to control the function of the filter unit but also to influence the effectiveness and quality of the device 1 be used.

Die Sensoreinheit 17 ist am Reinigungskanal 9 angeordnet und misst die durch die Rückspülung aus dem Siebfilter 5 ausgeschiedene Schmutzmenge. Die Sensoreinheiten 18 und 19 sind dem Siebfilter 5 zugeordnet und messen das für seine Drehung um die Achse 12 erforderliche Antriebsmoment bzw. den Siebflächenverbrauch oder die erforderliche Filterflächenkapazität während der Reinigung der Schmelze. Mit den Sensoreinheiten 20 und 21 werden noch die Viskosität der gereinigten Schmelze und die Wertung der Schmelzereinheit ermittelt. Weitere Meßgrößen, etwa Temperatur, Druck, elektrische Leitfähigkeit der Schmelze u. a. können alternativ oder zusätzlich ermittelt werden.The sensor unit 17 is on the cleaning channel 9 arranged and measures the through the backwash from the strainer 5 eliminated amount of dirt. The sensor units 18 and 19 are the sieve filter 5 assigned and measure that for its rotation about the axis 12 Required drive torque or the Siebflächenverbrauch or the required filter surface capacity during the cleaning of the melt. With the sensor units 20 and 21 are still the viscosity of the purified melt and the evaluation of the melt unit determined. Other parameters, such as temperature, pressure, electrical conductivity of the melt, among other things, can be determined alternatively or additionally.

Die von den Sensoreinheiten ermittelten, und ggf. daraus über Rechenmodelle errechneten Daten werden zunächst wie im Stand der Technik (2) an eine Filtersteuerung 22 übermittelt, mit deren Hilfe die Bewegung des Siebfilters 5 einstellbar ist. Des weiteren werden die Daten jedoch erfindungsgemäß an eine Prozesssteuerungseinheit 23 übergeben, die zwei Funktionen erfüllt: Zum einen regelt sie mit den gewonnenen Daten die Zusammensetzung der Komponenten im Materialinput, etwa derart, dass sie bei einem zu hohen Anteil einer Komponente in der Schmelze, etwa erkannt durch eine zu hohe Dichte oder fehlerhafte elektrische Leitfähigkeit, die Zuführung dieser Komponente verringert; zum anderen regelt die Prozesssteuerungseinheit 23 Verfahrensparameter 29 wie z.B. die Viskosität für die Vorrichtung 1 selber, wie hier dargestellt, und/oder für zumindest eine der Vorrichtung 1 nachgeschaltete Weiterverarbeitungseinheit, wie z.B. für einen Häcks ler, ein Ventil, einen Extruder o.ä. Zugeführte Komponenten können sowohl Recyclate als auch frische Materialien als auch eine Mischung sein, die zudem mit verschiedenen Füllstoffen angereichert sein kann.The data determined by the sensor units and possibly calculated therefrom by means of computer models are first of all as described in the prior art ( 2 ) to a filter controller 22 transmitted, with the help of which the movement of the sieve filter 5 is adjustable. Furthermore, according to the invention, however, the data is transferred to a process control unit 23 On the one hand, it regulates the composition of the components in the material input with the data obtained, for example in such a way that they are detected when too much of a component in the melt, for example due to too high a density or faulty electrical conductivity, reduces the delivery of this component; on the other hand, the process control unit regulates 23 process parameters 29 such as the viscosity for the device 1 itself, as shown here, and / or for at least one of the device 1 Downstream processing unit, such as for a chopper ler, a valve, an extruder, etc. Supplied components may be both recycled and virgin materials, as well as a mixture which may also be enriched with various fillers.

Insbesondere werden die Steuerungsbefehle für den Materialinput und die Filtersteuerung in wechselseitiger Abstimmung herausgegeben: Wenn zum Beispiel minderwertiger Ruß als zugeführte Komponente verwendet wird, der agglomeriert oder klumpt, bleiben diese Rußklumpen im Siebfilter 5 hängen und tragen nicht, wie gewünscht, zur Schwarzfärbung des Endprodukts bei. Der Siebfilter 5 verstopft daher schneller, und die Filtersteuerung 22 gibt somit den Befehl, die Eigenreinigung des Filters 5, also die Drehung um die Achse 12, zu beschleunigen. Gleichzeitig würde jedoch etwa durch dem Siebfilter 5 nachgeschaltete Sensoreinheiten 20, 21 die Fehlerhaftigkeit des Produkts an sich – hier zu geringe Schwarzfärbung – erkannt und von der Prozesssteuerungseinheit 23 somit die Information an den Materialinput herausgegeben, den Anteil der Rußkomponente zu erhöhen.In particular, the control inputs for the material input and the filter control are issued in mutual agreement: For example, if inferior soot is used as the feed component that agglomerates or clots, these soot clumps remain in the strainer 5 do not and do not contribute to the blackening of the final product as desired. The sieve filter 5 therefore clogged faster, and the filter control 22 thus gives the command, the self-cleaning of the filter 5 So the rotation around the axis 12 , to accelerate. At the same time, however, would be through the strainer 5 downstream sensor units 20 . 21 the defectiveness of the product itself - here too little blackening - recognized and by the process control unit 23 Thus, the information to the material input issued to increase the proportion of carbon black component.

Dabei sind Grenzwerte in die Regelung eingebaut, die zum Beispiel eine zu hohe Drehgeschwindigkeit des Siebfilters 5 oder eine zu hohe Dosierung einzelner Komponenten verhindern. Ggf. wird ein Alarm ausgelöst oder die Anlage automatisch abgeschaltet.There are limit values built into the scheme, for example, a too high Drehge speed of the sieve filter 5 or prevent too high a dosage of individual components. Possibly. an alarm is triggered or the system is switched off automatically.

Neben den Sensoren 17, 18, 19, 20, 21 sind auch verschiedene Regelglieder 24, 25, 26, 27 vorgesehen, die eine Regelung von Verfahrensparametern der Vorrichtung 1 ermöglichen, die im Betrieb eine Anpassung an detektierte Veränderungen ermöglicht. Etwa kann durch den als Ventil ausgebildeten Aktor 24 der Rückspuldruck eingestellt werden und durch den Aktor 25 die Druckdifferenz über die Siebscheibe 5. Die der Drehachse 12 zugeordneten Aktoren 26, 27 sorgen für eine Einhaltung von Grenzwerten für die Schmelzeverweilzeit am Siebfilter 5 und für eine Einhaltung von Grenzwerten für die Schmutzkuchenverweilzeit am Siebfilter 5.Next to the sensors 17 . 18 . 19 . 20 . 21 are also different rules 24 . 25 . 26 . 27 provided that a regulation of process parameters of the device 1 allow for adaptation to detected changes during operation. For example, by the trained as a valve actuator 24 the Rückspuldruck be set and by the actor 25 the pressure difference across the screen disc 5 , The axis of rotation 12 assigned actuators 26 . 27 ensure compliance with limit values for the melt residence time at the sieve filter 5 and for compliance with cut-off cake residence time limits on the mesh filter 5 ,

Es versteht sich, dass verschiedene Möglichkeiten der Beeinflussung des Prozesses durch die Prozesssteuerungseinheit 23 und zugehörige Aktoren eingestellt werden können.It is understood that various ways of influencing the process through the process control unit 23 and associated actuators can be adjusted.

Insgesamt kann damit der Prozess sich erstmals als Ganzes – und nicht nur die Parameter der Filtereinheit – selbst vollautomatisch regeln. Ein manueller Eingriff ist dabei nicht mehr erforderlich.All in all This allows the process to be considered as a whole for the first time - and not just the parameters the filter unit - itself fully automatic control. A manual intervention is not more required.

Der Vorteil liegt darin, daß man den Filter immer maximal nutzen kann, in dem die Dosierung der zuzuführenden Komponenten als auch die Verfahrensparameter automatisch optimal angepasst werden.Of the Advantage is that one the filter can always maximize use, in which the dosage of the supplied Components as well as the process parameters automatically optimally be adjusted.

Die von der oder den Sensoreinheit(en) 17, 18, 19, 20, 21 ermittelten Daten können zudem bei Hinweis auf etwa Qualitätsmängel in den zugeführten Komponenten als automatisierte Informationen nicht nur den Prozeß selbst beeinflussen, sondern auch gleichzeitig oder zeitversetzt an das Qualitätsmanagement 28 und/oder den Einkauf geliefert werden, um somit bei der nächsten Lieferung der entsprechenden Komponente eine Verbesserung zu erreichen.The of the sensor unit (s) 17 . 18 . 19 . 20 . 21 In addition, when data about the quality defects in the components supplied as automated information are obtained, they can not only influence the process itself, but also simultaneously or with a time delay to quality management 28 and / or the purchase so as to achieve an improvement in the next delivery of the corresponding component.

Es besteht aber auch die Möglichkeit, das Finalprodukt 30 entsprechend zu klassifizieren und zuzuordnen.But there is also the possibility of the final product 30 to classify and allocate accordingly.

Die Erfassung all dieser wesentlichen Daten stellt die konsequente Weiterverwertung der Prozessdaten dar, die sich aus dem filterspezifischen Kontrollsystem ergeben und die nunmehr zusätzlich eine umfassende und vor allem vollautomatische Prozeßsteuerung des gesamten Produktionsprozesses ermöglichen.The Capturing all this essential data represents the consistent re-use the process data resulting from the filter-specific control system result and the now additionally one comprehensive and above all fully automatic process control of the entire production process enable.

Voraussetzung für eine solch komplexe Steuerung ist ein Filter, wie er z.B. durch die WO 01/43 847 zum Stand der Technik gehört, bei dem das Schmutzkuchenprofil im Schmelzkanal zeitlich konstant ist und der Filter somit ein nahezu analoges Signal für die benötigte Filterfläche pro Zeiteinheit liefert.requirement for one such complex control is a filter such as e.g. by WO 01/43 847 belongs to the state of the art, in which the dirt cake profile in the melt channel temporally constant is and the filter thus a nearly analog signal for the required filter area per Time unit supplies.

Bei anderen Filtriersystemen kann man dies auch rein theoretisch aus dem Druckanstieg pro Zeiteinheit ableiten, dieser ist jedoch nicht linear mit der Schmutzmenge verknüpfbar, so daß eine solche Berechnung theoretisch sehr kompliziert, und daher in der Praxis nicht umsetzbar ist. Bei Rückspülfitern ist dies zudem überhaupt nicht umsetzbar, da die rückgespülten Siebe immer einen undefinierten und auch nicht kontrollierbaren Zustand haben.at This can also be done theoretically from other filtration systems Derive the pressure increase per unit time, this is not linearly linked to the amount of dirt, so that such Calculation theoretically very complicated, and therefore in practice is not feasible. For backwashers is this anyway not feasible, since the backwashed sieves always an undefined and uncontrollable state to have.
